TBI to TPI conversion
Alright, it's been a while since I've done anything to my car. I need assistance on this conversion. I need a lost of all things needed to complete this project and get it running.
Engine has been built, 305ci bored .030, mild cam, port and polished heads. I have a (1227165) MAF TPI system w/jet performance chip 18813, wire harness, intake manifold, runners, plenum, it was originally a TBI system.
What else will I need to fully complete this project?
IF there's a list of parts that I will need please advise. It will be greatly appreciated. Or maybe a link to a thread where all this is listed. I found a great detail list for a speed density TPI system, but I'm not sure if those parts are equivalent to the MAF TPI system.

Re: TBI to TPI conversion
Just a high pressure fuel pump should be it. Do you know what year your harness is for?
I believe there is a tech article on installing TPI on non-tpi cars

Re: TBI to TPI conversion
Off the top of my head :Intake gaskets, TPI gasket set, Throttle body, TPI Throttle cable, TPI fuel lines, fuel injectors ( if you already have them they may need to be cleaned if they have been setting any length of time) MAF Sensor, TPI air cleaner setup.. and a bunch of other little things that you haven't thought about...

Re: TBI to TPI conversion
Not quite sure it goes with ECM 1227165, from what I've read is that, this is a 86-89 System. I'm actually looking for a clear pinout schematic to make a new harness or eliminate things that I'm not using. Like for instance I have T-5 transmission so I would eliminate the A/T wires, A/C and power Steering as well as. I'm trying to keep it pretty simple.

Re: TBI to TPI conversion
Not sure what year harness you have but here lists the c110 and c207 for both 1987 and 1989. Big difference on an 89 as it doesn't have a cold start injector http://www.austinthirdgen.org/?pid=19 Not hard to remove a/t wiring and add m/t reverse wiring also
